Abbasi can certainly have "his" opinion. However when we said this:
we hate all Americans, “......... “From the bottom of our souls, we hate you.
he definitely stepped over the fine line of journalistic ethics. Him being a Pakistani makes it $tupeed to start a statement as "We hate................". This is so primitive and uncivilized.
Going back to the CNN example, Wolf Blitzer can have his "personal" opinion about hating all Pakistanis, or hating all Muslims.
But Wolfie needs to set that aside when he is interviewing a Pakistani dignitary.
Perhaps it is too difficult for you to understand the norms of "civilized behavior".
When he said WE, he meant he and his mindset, you need not to worry, there are many in Pakistan which can do every thing ( ofcourse if paid well) for USA.. so you can relax and have a chill pill
